There's a phase 3 trial for treating pneumonia associated with coronavirus. This is based on prior work showing anti-inflammatory response in rheumatoid arthritis (https://www.ncbi.nlm.nih.gov/pubmed/8278823).
Note that the trial is happening in China (https://clinicaltrials.gov/ct2/show/NCT04261517), where the barriers of entry and approval are quite low.

Huh. I'm on 200mg/day for rheumatoid arthritis.
I wonder if I ought to double dose for a while.
There are a fair amount of studies who took the initial in vitro results (i.e. cell culture) suggesting non-specific antiviral activity (at that level coca-cola is also an antiviral, antimicrobial, and antitumoral, by the way), into animal or human, and they just did not pan out, because it isn't an antiviral.
I'll ask my rheumatologist about increasing the dose. In case I get infected, have trouble breathing, and can't get hospital care.
